Title: Discharge port device for pump
Inventor: NAGASHIMA TAKAO
IPC: F04B53/10
Filed: 1991-06-17
Abstract: PURPOSE:To enhance the durability by allowing water which has been rectified by a check-valve to flow into a ball-like valve. CONSTITUTION:A check-valve 43 is arranged on the flow axis of fluid, and a ball valve 45 is arranged on the part of the flow axis which is folded back by about an angle of 90deg., downstream of the check-valve 43, at a height substantially the same as that of the latter. Accordingly, water having flown in a valve seat 35 is folded back by a substantially right angle by means of the upper and lower surfaces of the check valve 43 and the inner surface of a body 37 on the check valve 43 side, and is led into the ball valve 45 side. Thus, the force acting upon the ball-like valve 45 becomes uniform when a discharge port 36 is blocked by the ball valve 45 so that no useless force is exerted thereto, and accordingly, the durability of the ball valve 45 can be enhanced. Further, since the ball valve and the check valve are held substantially at the same height, the height of the discharge port of the flow passage, measured from the ground becomes lower, and accordingly, a reaction force during water discharge can be decreased.

Title: Frequency dividing circuit
Inventor: SUGIYAMA YUKINORI
IPC: H03K23/00
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent operation frequency from being reduced by providing this frequency dividing circuit with 1st and 2nd flip flops(FFs) and a logic circuit and automatically setting up the 2-frequency divided signal of an input signal and the 2n-frequency divided signal of the input signal to specific states. SOLUTION: In the FFs 13, 14, the FF 13 is regarded as an upper bit and 00→01→10→00→... are repeatedly counted up. If a CLK signal is raised when a data output from the FF 13 is '1', the FF 14 inverts the data output, but when the output of the FF 13 is '0', the FF 14 does not change the data output even when the CLK signal is raised. Thereby an output from a three-input NAND 16 becomes '1' only in a specific state of a 6-frequency divider, i.e., the state of a counter constituted of the FFs 12, 13 is 00 and the output of the FF 14 is '0'. If a data input signal to an FF 11 is masked to '1' by a two-input NAND 15 when the signal is '1', a 2-frequency divider can be initialized to a specific state when the 6-frequency divider is in the specific state and phase matching between a 2-frequency divided signal and a 6-frequency divided signal can be executed.
